The Cessna 421 Golden Eagle is a development of the earlier Cessna 411 light, twin-engine personal transport aircraft. The main difference between the two models is that the 421 is pressurized.[1]

[edit] Development

The 421 uses geared Continental GTSIO-520-D engines. The gearing means that rather than the drive shaft being directly connected to the propeller, it drives through a set of reduction gears.[1]

The 421 was first produced in May 1967. The 421A appeared in 1968 and the aircraft was redesigned in 1970 and marketed as the 421B. In 1975 the 421C appeared which featured wet wings, the absence of wing tip fuel tanks and landing gear that was changed from straight-leg to a trailing-link design. Production ended in 1985 after 1901 had been delivered.[1]

The Cessna 421 was first certified on 1 May 1967 and shares a common type certificate with models 401, 402 411, 414 and 425[2]

Some 421s have been modified to accept turboprop engines, making them very similar to the Cessna 425, which itself is a turboprop development of the 421.[citation needed]
